Wearables

Scalable, Power-Efficient, & Highly Integrated Solutions for Next-Gen Wearables

For modular solutions across health, access, and lifestyle wearables, Renesas offers complete system solutions for wireless and connected devices in a wide range of compact form factors. From smart rings for contactless payment to user badges for secure access and safety tracking, our portfolio of industry-leading Bluetooth® Low Energy SoCs for ultra-low power consumption, high-efficiency PMICs to extend battery runtime, and configurable mixed-signal ICs (GreenPAK™) that consolidate analog, timing, and logic functions into a single compact device, Renesas empowers wearable innovation by streamlining development, reducing design complexity, and delivering performance without compromise on size, power, or functionality.

Ultra-Low Power Consumption

Design wearables with some of the lowest-power Bluetooth LE SoCs and complete your designs with efficient power management ICs and GreenPAK devices for longer battery life, smaller form factors, and reduced charging frequency.

 

Multifunctional Devices for Small Form Factors

Simplify wearable design with analog and mixed-signal integration across GreenPAK ICs and Bluetooth LE SoCs. Consolidate functions such as op amps, comparators, ADCs, and logic into small and compact packages to reduce board size for small and sleek wearables.

Comprehensive Connectivity

Enable always-on, low-power connectivity for wearables with Bluetooth LE SoCs supporting multi-role operation and long-range capabilities and optional NFC integration for tap-to-connect features like secure authentication and data exchange.

Modular Scalability Across Form Factors & Use Cases

Our portfolio of MCUs, Bluetooth LE SoCs, PMICs, sensors, and configurable logic devices are designed to scale across multiple wearable types, supporting design reuse, simplified system upgrades, and accelerated time-to-market.

Wearables Applications

Connected Monitoring

Connected Monitoring

Reliable, Always-On Connectivity to Mobile Devices

Wearables must continuously transmit data—like health metrics or access credentials—without draining power or losing signal. Engineers need long-range, stable, low-power communication that integrates easily with mobile platforms.

Our Bluetooth LE SoCs offer multi-role support and long-range capability for reliable connectivity to mobile devices. With high receive sensitivity, they maintain stable connections even in noisy environments or when worn under clothing. High transmit power enhances range and signal strength, ensuring continuous data transmission for critical monitoring applications.

Packing More Functionality into Lifestyle Wearables & Smart Accessories

Today's smart accessories must go beyond time and step tracking to support NFC payments, real-time app syncing, gesture or touch control, and biometric tracking—all in sleek, compact designs. Developers face the challenge of maximizing performance and user experience within strict power and size constraints.

We help with our multifunctional, ultra-compact Bluetooth LE SoCs to combine processing, communication, and control in tiny packages (like WLCSP: 3.32 × 2.48 mm), and GreenPAK™ solutions consolidating logic, passives, and more into a single IC.

Delivering High-Quality Audio in Ultra-Compact Designs

Wearables like earbuds and smart headsets demand exceptional audio performance, but space, battery, and thermal limitations make integration difficult. Balancing hybrid active noise cancellation (ANC), low-latency wireless audio, and clear voice pickup within a small form factor is a complex task.

We provide high-fidelity, low-latency audio solutions for compact, battery-powered devices. From low-power, multi-stream support with stereo playback to advanced noise management supporting flexible ANC topologies, integrate our audio solutions for immersive, high-quality audio.
